YouTube's auto-captioning system is notoriously unreliable, with accuracy rates ranging from 60-70%, which means that up to 30% of captions may be incorrect. This has significant implications for content creators who rely on accurate captions, particularly in educational and potentially life-saving videos. To address this issue, Speechmatics has developed an AI-powered speech-to-text engine that demonstrates significantly higher accuracy rates, with some tests showing levels above 90%. The company's self-supervised learning approach allows it to improve its engine by incorporating a vast amount of unlabeled data, which helps bridge the gap between well-curated and everyday speech. As captioning becomes increasingly important, the market is shifting towards innovation, prioritizing accuracy, and making captions a necessity rather than an add-on.
